The controversial documentary filmmaker has been exceedingly vocal against the Trump presidency, appearing at anti-Trump rallies and even making another documentary about modern America in 2016’s Michael Moore in TrumpLand.

In the trailer, Moore is seen spraying what appears to be water from Flint, Mich., onto the front lawn of Michigan governor Rick Snyder; Flint, where Moore was born, is still without clean drinking water.

In Fahrenheit 11/9, Moore also speaks to student activist David Hogg, a survivor of the Stoneman Douglas High School shooting in February, and Alexandria Ocasio-Cortez, a Democratic congressional candidate who recently won a stunner in the primary.

The title of the movie is a play on words, and a reference to Moore’s earlier movie Fahrenheit 9/11, which examined the presidency of George W. Bush and his “war on terror” following the Sept. 11, 2001, attacks in New York City. It remains the highest-grossing documentary of all time with US$222 million in worldwide box office.

The filmmaker won an Oscar in 2003 for his gun-violence documentary Bowling for Columbine, and was nominated for an Oscar in 2008 for Sicko, an indictment of the U.S. health-care industry.
